Severity by source

No source gives a CVSS score.

Trivy's own label is CRITICAL. Rated critical by GHSA.

Description

All versions of `parsel` use an insecure key derivation function. The package runs keys of arbitrary lengths through one round of SHA256 hashing for key stretching. This allows for the use of keys of insufficient entropy with inappropriate key stretching. ## Recommendation The package is deprecated and will not be updated. Consider using an alternative package.

What Attestkeep does with this

Inside your cluster, without you opening a spreadsheet.

KnowsThe scanner refreshes its vulnerability database every six hours.
FindsEvery admitted image is rescanned every 24 hours by default (scan.rescanInterval). When Trivy rates this vulnerability critical for the image's package source, it appears in the image's findings by name. Findings without a fix are left out unless includeUnfixed is on.
Tells youA critical_finding event goes to the channels subscribed to it: e-mail, Slack, Teams, a webhook, Jira, GitLab or GitHub.
RefusesWith a policy that blocks critical findings, a pod with this image is refused at admission, a rollback to it included. Pods already running are not evicted.
RecordsEach decision is recorded with the policy that ran and its hash, then sealed under a signed checkpoint.
